v battery having cells with improved means for charging, w1thdraw1ng and circulatmg.

the solutions and making the electrical connections, the apparatus being readily constructed', connected 'and separated and eiicient in operation.

T he nature and characteristic features of the improvements will more fully appear by reference to thefollowingV description and the accompanying drawings in illustration there of, of which:

Figure 1 vis a plan viewof a pair of connected cells embodying the improvements: Fig.`

2 is a vertical sectional view of the bottom of a cell,l taken on the linef2-2'of Fig. 1, show-V ing a section of an electrode therein: Fig. 3 is a vertical sectional view of the bottom of a cell, taken on the line 3-3 of Fig. 2: Fig. 4 is a plan view of two connected cells embody ing a modified form of liquid conduits and connections: Fig. 5'is a vertical-sectionalv view of the bottom of a cell taken on the line 5-5 of Fig. 4: Fig. 6.is a verticalsectional Niew ofv the bottom of`two connected'cells, taken on the line 6 6 of Fie. 4, showing electrodes and compartments t ereof: Fig. 7 is a vertical sectional'view of the bottom of a cell, taken on the line 7 7 of Fig.'4: and

8 is a transverse vertical sectional view showing diagrammatically a cell divided into two sets of compartments with the several compartments of each set connected with a"con' duit.

I In the apparatus, the respective cells comprise the envelope 1, suitably composed of.

hard rubber, having in their bases 1" depressions comprising the channels 2 with pits 3 in the bottom thereof, the insulating closed conduit'4 with the exterior port 5 and the in-` terior port 6, and the insulating closed coni duit 7 4with the exterior port 8 and the interior ports 9.

The conduits 4 arid 7 of small caliber and length ap roximately that of the cell so that solution t erein shall havehigh electrical resistance are formed separately from the base 1f and are cemented thereto above the general level thereof. The ports 9 communivcate u ith the porous cups 37 through the. I

place by the shoulders 11 and the lugs 12 on y the interiors of the cells, have the contracted feet 10 depending into the channels 2adapted to make contact with the mercury de, posited therein. A

Conducting devices in the form of screws 13 engage the terminal conducting strips 14 with the bottom of the respective cells and extend into mercury deposited in the respective pits 3,k bywhich the electrodes are electrically connected in multiple with the terminal members 14, these members of juxtaposedv cells being y connected by binding screws-15.

As shown in Figs. 1, 2 and 3, the cells be-` ingplaced together, the exterior-ports 5 of the severalcondu-its 4 communicate with a main conduit 16 by the branches 1,7. thereof, the latter havingHangesA id endage'd' by sleeve 'nuts 19 sockets 2O of the lbase, and the exterior ports8 of the several conduits 7 communicate with the main `conduit 21 by the branches 22 thereof, the latter having flanges 23 held in sockets 24 of the base by Isleeve nuts 25. As shown iniFigs. 4 to 7, the ports 5 and 8 may communicate respectively with main conduits 26 and '27 formed in the base members 28, the corresponding conduits 26 of juxtaposed cells being connected by separable tubes 29 having thereon flanges 30 engaged by sleeve nuts 31 in sockets 32 of the base members, and the corresponding conduits 27 being connected in a similar manner by the separable tubes 33 having anges 34 thereon engaged by sleeve nuts 35 in sockets 36.- As shown in Fig. 8, the apparatus may be used with a single solution, in which case the solution is charged through'the port 6, rises tothe top of the cups or compartments 37, washesdown the sides thereof vas they are` filling, and may be drawn off /throligh the port 8.. t

vtrodes,

By the foregoing constructions I ain very readily enabled to assemble or separate the cells and their several parts and to distribute the solutions from inain conduits through leak proof connections directly to a plurality of cells each having therein insulating ininor conduits respectively distributing to a. plu

4 rality of compartments, providingr a co1npact,

practical and efficient scheine for han dling the solutions.

II aving described iny invention, I claini 1. In a battery, a cell having a base, an insulating conduit connected with said base, a plurality of compartments connected to said conduit, electrodes in said compartments, depressions in said compartments which receive the bottonis oi said eleca crmducting device extending through said base in registration with each of said depressions, and a conducting device attached to the exterior of 'said base in contact with each of said first conducting devices.

2. -In abattery, a plurality of juxtaposed -cells, an insulating conduit within the bot-- torn of' each cell, and an exterior main con duit havin lflanged branches with nuts` thereon, said cells having sockets wherein said -ange'd Abranches are secured /by said 4in said depressions,

nuts so that said main conduit communicat-es' with said interior conduits- In a battery, a cell having a base with, aset oi" inteiior depressions therein, an cxterior conducting strip, conducting screws passing through said strip and base into the respective depressions, and electrodes within said cells having depei'idnig parts disposed 4. In a battery, a cell, a base with parallel depressions therein, electrodes having parts .FRANK A. DECKER Witnesses:
